The Hip Joint

3.6 Blood Supply

Blood enters the head from three directions:

  1. Lateral:

    (+) trochanteric
    (+) cruciate anastomosis.

    They reach their destinations through the retinacula

  2. Medially from the obturator artery through the ligament of the head of the femur

  3. From the nutrient arteries running through the medullary cavity


This anastomosis persists even in old age but in 20 % it is never found
